Other drug treatments for cancer include immunotherapy and targeted therapy. Immunotherapy uses substances that encourage the body’s own natural defences (immune system) to fight disease. Targeted therapy attacks specific features of cancer cells to stop the cancer growing and spreading.
Side effects for these treatments vary depending on the particular drug that is used, but can include swelling, weight gain, fatigue, pain, and depression, all of which may affect your desire for or ability to have sex. Your doctor will explain if you need to use protection during sex after having these therapies.
